Channel separation and crosstalk

Figure 65 shows an example of crosstalk from one amplifier to a second amplifier. This

phenomenon, accentuated at high frequencies, is unavoidable and intrinsic to the circuit

itself.

Nevertheless, the PCB layout also has an effect on the crosstalk level. Capacitive coupling

between signal wires, distance between critical signal nodes and power supply bypassing

are the most significant factors.
